The Mazda PEXP is a 2,488 cc, inline‑four turbocharged petrol engine produced from 2021 to present. It features Skyactiv-G technology with a 10.5:1 compression ratio, direct fuel injection, and a twin-scroll turbocharger, delivering 187–189 kW (253–256 PS) and 434 Nm of torque for strong, linear acceleration and effortless overtaking. The twin-scroll turbo design minimizes lag, providing responsive power delivery across the rev range.
Fitted exclusively to the CX-60 and CX-70 platforms, the PEXP was engineered for premium mid-size SUVs, offering a blend of refined power, towing capability, and engaging dynamics. Emissions compliance for Euro 6d standards is achieved through a sophisticated engine management system, cooled exhaust gas recirculation (EGR), and a gasoline particulate filter (GPF).
One documented service consideration is the potential for carbon buildup on intake valves, a known characteristic mitigated by the engine's design but noted in Mazda Service Information Bulletin SI-005-21 for preventative maintenance. This engine represents Mazda's flagship petrol powertrain for larger vehicles, succeeding the naturally aspirated Skyactiv-G units.

The twin-scroll turbo provides strong, lag-free torque ideal for towing and highway driving but requires strict adherence to 0W-20 API SP specification oil to protect internals and maintain GPF function. While designed to minimize carbon buildup, periodic inspection of the intake system is advised. The timing chain is designed for the engine's lifespan. Premium (95 RON) fuel is recommended for optimal performance and to prevent knock under high load.
Oil Specs: Requires API SP / ILSAC GF-6 0W-20 oil (Mazda Owner's Manual CX-60 Series). This viscosity is critical for fuel economy and emissions system protection.
Emissions: Euro 6d certification applies to all production years (VCA Type Approval Records).
Power Ratings: Measured under JIS or DIN standards depending on market (Mazda Group PT-2024). Output is consistent across markets.

The Mazda PEXP was developed for Mazda's new rear-wheel-drive-based Large Product Group platform with longitudinal mounting. This engine is exclusive to premium SUVs and features specific calibration for the mild-hybrid system. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the engine block, near the timing cover (Mazda Workshop Manual CX-60 Series). The code will read "PEXP". Visually, it can be identified by its "SKYACTIV-G 2.5T" branding on the plastic engine cover and its longitudinal mounting in the engine bay. The presence of a gasoline particulate filter (GPF) is also a key identifier. Parts compatibility is exclusive to the CX-60 and CX-70 platforms; confirm specific part numbers using the VIN.
The PEXP's primary reliability consideration is maintaining the gasoline particulate filter (GPF) and using correct oil specifications. As a new engine, long-term data is limited, but Mazda's internal design reviews indicate robust mechanical reliability. Adherence to specified oil grades and driving patterns that allow for passive GPF regeneration are critical for sustained performance.
